Since I have been a "What do you want to know that fore?"- kindda person al my life, and a quick google search didn't turn up the answer, I decided to ask in the gear & rigging section in case anyone here knows.

No clue as to the answer, but I can tell you this, We have a russion "presure suit" and it's quite light. Not heavy at all. Normally I think of "space suits" as very heavy bulky combersom things but this is not. No real insolation, It doesn't have the full "suport system" that you would think of, AC and heating, etc. And the aproach to it's construction is much diffrent and so much simpler. It does have constant volume joints, sort of. They use a system where they have a loop of cable that runs through a curved sleave pulling a pleate in the joint. So the joint can move in an arc compressing on one side and expanding on the other. Very simple and light. Rather then building a custom suit they use a laceing system to compress it in a number of dementions. It will fit a wide range of people. And it is a full presure suit rated for full vacume.

In any case I don't know the answer but there are some lighter weight options out there. It's just really cool. I almose shit my self when I walked around a corner one day and saw this thing just gathering dust in the corner of the shop there at Armadillo. I like walk past it setting in a pile on a landing at the top of the stares. At first I had no clue what the pile was then I saw one of the rings to attach the gloves and I do this big double take. I was drawn to the thing like a magnet. Phill notices that I'm not following him and calls back over his shoulder, "Oh yah, that's one of the Russion preasure suits, come on I'll show you what we need sewn on... shuch and such." I don't remember if he had to drag me away by my collor or not. I wasn't really seeing or hearing any thing at the time. My mind was filled with visions of the moon. Have space suit will travel. Did I ever mention that thouse guys have way too many toys. Don't even get me started on the pulse jet powered go cart.

This has totaly digressed. Just pointing out that there are some really striped down options out there. The things are around.

Felix’s full-pressure suit and helmet acted as a ‘personal life support system’ and it was modeled on suits worn by high-altitude reconnaissance aircraft pilots, but was custom-made to suit his measurements and upgraded with the latest technology. The total weight of the gear is a hefty 70 pounds including the helmet that was 8 lbs.
